Oil Filter - A & I Products

Filter uses cellulose/glass blend media to protect engines by trapping and holding contaminant particles and preventing them from entering vital engine parts. The louvered centertube not only provides internal element support and strength, but also allows maximum flow. A steel coil spring maintains a constant load pressure, protecting engines, even during pressure surges. A by-pass valve protects the engine in cold starts and highly restrictive conditions by making sure lubricants are distributed to vital engine parts. An anti-drainback valve keeps oil in the filter, preventing engine-destroying dry starts.
